Actually, we still recommend a professional high voltage detector for serious work, but you’ve got to like this electric field detector that [Alessandro] recently put together. The detector ...

Some of the most sensitive methods of measuring magnetic fields use interactions of resonant light with atomic vapour. Recent developments in this vibrant field have led to improvements in ...

The magnetic field causes metal objects underground to give off their own magnetic fields, which the detector coil can read. The detector can determine how far underground an object is based on ...

Electrets produce a semi-permanent static electric field, similar to how a magnet produces a magnetic field ... He built a simple electric field detector, which is just a battery, LED and FET ...

Treating diabetes often involves daily pills or insulin injections, but a study published this week (October 6) in Cell Metabolism presents another potential treatment option: electromagnetic fields.

whose shape stored electric fields inside, producing hotspots in which plasma forms. Fawaz suspected the accompanying magnetic fields would be useful where microwave radiation is used to trigger a ...
